Hello!
Hi!
I have data warehouse application(base on oracle database), i want to
transfer it to hbase database ,how to design hbase tables especially 1:n or n:m
relationship in oracle database !
Thank U very much!

Are you running hbase in standalone mode ?
See http://hbase.apache.org/book.html#zookeeper
bq. To toggle HBase management of ZooKeeper, use the HBASE_MANAGES_ZK variable
in conf/hbase-env.sh.

Hi Ted,
Thanks for your reply. Yes i am running standalone mode
After changing my zookeeper property its resolved .And now i have another
two issues .

Dear All,
Suppose that I have a key range from 1 to 100 and want to store 1-50 in the
first node and 51-100 in the second node. How can I do this in Hbase?
regards!

Hi Yong,
Check out http://hbase.apache.org/book/perf.writing.html to learn about
pre-splitting regions at table creation time. Beyond this, HBase internally
handles which RegionServers serve any particular region.
All the best,
Dima

Oops, accidentally cut out my last sentence:
If you do want to move a region manually, the simplest way to do this is by
invoking move in the HBase shell.

Hi, I'm migrating from CDH4 to CDH5 (hbase 0.98.6-cdh5.2.0)
I had a unit test for mapper used to create HFile and bulk load later.
I've bumped maven deps from cdh4 to cdh5 0.98.6-cdh5.2.0
Now I've started to get exception
java.lang.IllegalStateException: No applicable class implementing

Can you reveal how PutFactory creates the Put ?
Thanks

In the 0.94.x API, Put implemented Writable[1]. This meant that MR code,
like yours, could use it as a Key or Value between Mapper and Reducer.
In 0.96 and later APIs, Put no longer directly implements Writable[2].
Instead, HBase now includes a Hadoop Seriazliation implementation.
Normally, this
Since your code uses mrunit which hbase 0.98 is not dependent on, have you
considered asking this question on:

I use it to prepare HFile using my custom mapper emitting Put and

and then bulk load data to table using LoadIncrementalHFiles
P.S.
HFileOutputFormat is also deprecated... so many changes... (((
If you're calling HFileOutputFormat.configureIncrementalLoad, that should
be setting up the Serialization for you.
Can you look at the job configuration and see what's present for the key
io.serializations?

Incidentally, you should consider switching to HFileOutputFormat2, since
you rely on the version that has a Mapper outputting Put values instead
Sean, I've started to catch that serialization problem on unit-test level
while using mrunit.
I don't see any possibility to call HFileOutputFormat.configureIncrementalLoad
before mrunit mocking stuff.
I was workngi w/o any problem in 0.94 :)

No, that's all details on the update to the backing HFile format that
started in HBase 0.92. The change in output format is detailed here:
bq. context.write(hbaseKey, put); //Exception here
I am not mrunit expert. But as long as you call the following method prior
to the above method invocation, you should be able to proceed:
conf.setStrings(io.serializations, conf.get(io.serializations),

You have ~280 regions per RS.
And ur memstore size % is 40% and heap size 48GB
This mean the heap size for memstore is 48 * 0.4 = 19.2GB ( I am just
considering the upper water mark alone)
If u have to consider all 280 regions each with 512 MB heap you need much
more size of heap. And your
Hi, all,
I have a program to calculate the disk usage of hbase per table in hbase 0.94.
I used to use the hadoop fs -du command against directory $roodir/table as

http://hbase.apache.org/book/trouble.namenode.html .
However, when we
In 0.98, you would find your table under the following directory:
$roodir/{namespace}/table
If you don't specify namespace at table creation time, 'default' namespace
would be used.

Is there any best practices or ready solutions for HBase?
